    Tool Tethers


    Tool tethers have been around for quite a few years. However, traditionally they were referred to as tool lanyards. The industry has adopted the name tool tethers to prevent confusion between tool drop prevention equipment and shock absorbing lanyards. Tool tethers, like most equipment in the at-height industry, come in a range of shapes and sizes.

    How They Work


    Dropped objects are still a huge cause of injury and death in the United States. Tool tethers are designed to help prevent those casualties and also prevent lost productivity and damaged equipment.

    Tool tethers have a range of connections points and a variety of different weight capacities ranging from 1 to 15 pounds. The weight capacity is based on the weight of the tool.

    If you need a tool tether with a larger capacity click here to contact one of our Gear Experts®.

    Connecting the tool tether to the tool itself can be done in a few different ways. If the tool has a tether connection built-in, then you are good to go. Simply attach the connection point of the tether to the tool and you’re in business. If you find yourself in a situation where the tool does not have a tether point, there are solutions available. Some options include:

    Self-Adhering Tape – This is a tape that has been designed to adhere to a connection point to your tool.

    Tool Collars – These are components that help retrofit a range of tools with a connection point without hindering the ability to use the handle of the tool.

    Tool tethers come in a range of lengths that not only provide easier use when working but also provide added force reduction in the event of a drop. Another option, if you need to be able to adjust the length, is to use a retractable tether. Think of retractable tethers as mini SRLs for your tools. It functions in much the same way.

  2. Product Spotlight: Petzl GRILLON PLUS Adjustable Positioning Lanyard

    Petzl Grillon

    Positioning yourself where you need to be will make the job a little bit easier when working at height. Beyond that, having the ability to adjust your positioning on the fly – while still maintaining 100% tie-off increases productivity while still maintaining safety standards. Adjustable positioning can be done with the use of specialty equipment and this week our Gear Experts® are going to break down the Petzl GRILLON PLUS Adjustable Positioning Lanyard.

    The Petzl GRILLON PLUS


     

    The GRILLON PLUS is similar to the traditional GRILLON. One of the major differences that you might notice is that the PLUS doesn’t have an abrasion sleeve. That’s because, instead of having a standard kernmantle rope construction, it’s made out of heavy-duty aramid fiber kernmantle rope. Aramid fiber rope provides superior resistance to abrasion when compared to nearly any rope which removes the need for the abrasion sleeve.

    Features


     

    Rope

    Not only is the rope stronger, thanks to the aramid fiber construction, but it also features sewn terminations at both ends. The ends are then covered in a plastic sheath to help keep the connector in position while simultaneously protecting the ends of the rope from abrasion.

    Adjustability

    The adjustability of the GRILLON PLUS is all thanks to the aluminum device that comes attached to the rope. This device is well known for its smoothness when allowing a rope to pass through it.

    Versatility


     

    The GRILLON PLUS is a versatile piece of equipment. It comes in two different lengths – 2 and 3-meter versions. And, if the rope ever needs to be replaced due to damage or any other reason, you can easily swap it out with a GRILLON PLUS Replacement Lanyard. Lastly, it can also be used in two different configurations (or, as we call them, modes). Those modes are double and single mode.

    Single Mode

    Single Mode is used when an anchor is directly above you. This mode will comfortably distribute the load between the belt and the leg loops. Your position can be adjusted by operating the handle while holding the free end of the lanyard.

    Double Mode

    When using the device in double mode, the lanyard is fed through the anchor or structure and the end is secured to one of your hip D-rings while the device is attached to your other D-ring. The double mode technique does a better job at distributing the load to the belt while allowing you to pivot and swing to achieve your desired position.

    Certifications


     

    This lanyard is fancy – no doubt about it. Between the top-of-the-line features and versatility, it’s a device that can come in handy for anyone who needs the ability to position while working at-height. But, perhaps the most important feature is the standards this device meets. It meets ANSI Z359.3, CSA Z259.11, CE EN 385, and CE EN 12841 Type C.

  3. Confined Space 101

    It’s no secret that working at-height, industry, and construction is dangerous. But confined spaces bring a whole slew of additional dangers. This week our Gear Experts® are going to break down confined space and talk about some of the important things to keep in mind/remember when working in confined space.

    What is a Confined Space


     

    A confined space is an area that has an opening large enough for a worker to access and enter to perform work. The area has a limited or restricted means of entry or exit and is not designed for continuous human occupancy. Because of the restricted means of entry and exit confined spaces are considered one of the most dangerous job sites. Some examples of confined spaces include underground vaults, sewers, tanks, storage bins, pits and diked areas, vessels, and silos.

    Confined Space Work


     

    It is important to know if your job site, plant, or shop requires confined space entry. If it does, you will need to ensure that you are following the appropriate safety precautions. Safety precautions include equipment that has been designed specifically for confined space applications (like a confined space kit). It’s also important to understand and be prepared for hazards that are common to confined space work.

    Hazards common to confined space work include unsafe air, toxic contaminants, electrical hazards, mechanical hazards like augers, and leading-edge fall hazards. While these are some of the common hazards, each confined space is unique and may feature some, all, or additional hazards that we haven’t listed in this post. Confined spaces should, under no circumstances, be entered unless you are trained and authorized and proper safety precautions have been taken.

    Safety First


     

    When it comes to confined space, the safety first mindset is extremely important. Untrained and unauthorized employees should never enter a confined space and a competent person should determine if the confined space is safe for entry before employees enter. Stay alert of changing conditions, know how to contact emergency services, and always have an emergency rescue plan in place.

    A safety first focus for confined space doesn’t have to be limited to inside the space itself. It’s also important to make sure to lockout and tag any mechanical equipment that could activate or energize while the confined space is occupied. You should also have the appropriate barriers and signs outside of the confined space to alert and prevent other people from entering or falling into the confined space.

    Equipment


     

    As we mentioned above, confined spaces vary in size, shape, location, and environment. That means that there isn’t a standard or typical application, so your confined space safety equipment must be flexible as well. Consistent anchorage is rarely found from one job to the next. Some confined spaces like a manhole on a street will require vertical equipment, but others like a tank would have a side-entry or horizontal requirement.

    Choosing the right confined space entry and rescue equipment can be difficult. Temporary jobs require lightweight and easy-to-use portable confined space systems. For areas that are accessed frequently a davit system with a permanently mounted base would be more ideal.

    Lifeline type and length are other variables to consider. In some situations, a back-up system may be required. Typical mechanical devices include man-rated winches and 3-way retracting lifelines with both fall protection and emergency rescue functions.

  4. RF 101

    When it comes to working in the telecom industry, it’s no secret that there are a wide variety of different dangers. Most dangers can be seen – whether it has to do with falling, having things fall on you, etc. But not all dangers are visible with the human eye – or even any human sense. This week our Gear Experts® are going to break down the hidden danger of RF.

    More Than Meets the Eye


     

    RF, or radio frequency, is any electromagnetic wave frequency. In the telecom industry, this is the energy that is emitted from radios or telecommunications equipment. Electromagnetic wave frequencies can’t always be seen or heard, but they are absorbed by your body and, if overexposed, can cause serious harm.

    The Dangers of RF


     

    So, now that we know what RF is and that just because we can’t see, hear, or otherwise sense, it doesn’t mean it isn’t dangerous. Let’s cover some of the effects of RF exposure. The primary effect is heating – think of it like a microwave oven which uses electromagnetic waves to heat food from the inside out. Keep in mind, that while a microwave does use electromagnetic waves to cook food, it is a very large amount of power being concentrated into a tiny steel box. Most telecom related RF situations will not be nearly as drastic as a microwave oven. However, the basic concept is the same. When the electromagnetic waves are absorbed by your body they heat it up from the inside out and you begin to experience RF sickness.

    Symptoms of RF Sickness


     

    RF Sickness won’t be noticed by most people right away. In fact, some people may never even realize they have it, which can cause added risk. The reason people don’t always know they have RF sickness is because the primary symptom is heat. It can be difficult to determine whether you may have RF sickness, or you simply haven’t been drinking enough water and might be dehydrated. With that being said, the symptoms of RF Sickness are most commonly compared to having a fever – making it even more difficult to detect.

    Effects of RF Sickness


     

    RF heats your body from the inside out. That means that as you are exposed to it, it is raising your core temperature. It’s not the same as standing next to a heater where you would feel the heat on your skin rather the heat would begin radiating outward from your core.

    As your core begins to heat and your body begins to lose the ability to prevent your temperature from rising you can start to experience heat stress. The symptoms of heat stress include rash, cramps, dizziness, headache, nausea, confusion, heavy sweating, weakness, seizures, and unconsciousness. We’ve covered heat stress in its entirety on a previous blog post which you can find by clicking here. 

    While all symptoms of heat stress are serious and should be treated immediately, we want to focus on confusion for just a second. Confusion also referred to as irrational behavior, can lead to costly mistakes and potentially fatal accidents. In fact, it is difficult to know if some tower fatalities were caused because of human error, or if confusion caused by RF sickness was to blame.

    RF Exposure


     

    The actual full breakdown of how the human body reacts to RF exposure can get pretty technical and is beyond the scope of a blog post. But, boiled down to its most basic explanation, our bodies are more receptive to lower frequencies. And, because of the way our bodies react to RF frequencies the way that safe exposure limits are expressed is more of a bell curve rather than a straight line. Beyond that, RF exposure tracking uses a 6-minute averaging rule.

    6-Minute Averaging Rule


     

    What the 6-Minute Averaging Rule means is that over the course of 6 minutes your average exposure level cannot exceed that of 100% of the FCC limits. Essentially, what this means is that you could have a brief period where you are at 150% of the FCC limits, but then for the next few minutes you are only at 25%. This is acceptable because the average exposure level over the course of 6 minutes is below 100%.

    FCC RF Limits


     

    As we mentioned above, the FCC has outlined limits for RF exposure that are calculated using the 6-minute averaging rule (0.1-hour periods). The FCC RF limits are applied to “normal environmental conditions and for incident electromagnetic energy of frequencies from 10 MHz to 100 GHz, the radiation protection guide is 10 mW/cm.(2) (milliwatt per square centimeter) as averaged over any possible 0.1-hour period.” Below is a breakdown of what this means.

    • Power density: 10 mW/cm2 for periods of 6 minutes or more
    • Energy density: 1 mW.-hr/cm2 (milliwatt hour per square centimeter during any 6-minute period.

    It is important to note that this guide applies whether the exposure is continuous or intermittent within the 6-minute averaging period.

    Limiting RF Exposure


     

    When it comes to limiting RF exposure there are two main components. The first component is proper training while the second component is a safety monitor.

    Proper Training

    Just like everything in the tower industry, training is an important part of ensuring safety. We have partnered with industry-leading training companies like Safety LMS to offer an online Fundamentals of RF/EME Radiation course. This course was designed to help ensure that employees can recognize the hazards of RF that exist on tower sites – whether that is a tower or a rooftop.

    RF Monitors

    An RF monitor complements training. After all, being trained to understand and handle a hazard is great, but when you cannot detect the hazard with your senses, it’s kind of hard to make sure you’re not exceeding safe exposure limits. One reason why an RF monitor is so important is that it is a shaped probe/shaped response device. What that means is that it has the ability to account for all RF frequencies in the surrounding area (like a rooftop with multiple different types of antennas) and calculate the amount of exposure from each. It then combines those numbers and bounces that against the safe working limits.

    With personal RF monitors like the FieldSENSE 2.0 Personal RF Monitor you can rest assured that you will be able to accurately detect RF. We covered the FieldSENSE 2.0 Personal RF Monitor in a previous blog post which you can read by clicking here.

    We recently featured Max Birch, the lead engineer for FieldSENSE, as our guest on our podcast: Gear Up with Gear Experts. Max dropped some knowledge bombs about RF and helped break down some of the complicated parts of RF awareness and safety. You can find that podcast episode by clicking here.

  5. Cadweld Demonstration


    Creating quality and reliable cable ground is an important part of the construction process. Using welding kits, like the Cadweld Plus Electronic Exothermic Welding Deluxe Kit can help ensure a proper, high-quality weld and keep you and your crew safe and productive on the job. This week our Gear Experts®  are going to break down how to use the Parallel Splice Mold and K-Cups from the Cadweld Plus Electronic Exothermic Welding Deluxe Kit to ground cable. For more information on the regular & plus kits, click here to check out a previous blog post.

    Cadweld Connections


     

    A Cadweld connection has a carrying capacity equal to or greater than that of the conductor and will withstand repeated fault currents without failing during operation. Cadweld connections also consistently exceeded IEEE® 837 2014 EMF test requirements and have been certified by an independent lab.

    Prep


     

    Prep is equally as important because it can prevent accidents from happening. To prep for the weld, be sure to thoroughly clean the mold and copper wires using an approved Cadweld Mold Cleaning BrushAdditional cleaning of the copper wire with a wire brush may be required to remove any grit or corrosion. Next, preheat the wire and the mold using a heat torch. This will get rid of any excess moisture that could negatively affect the weld quality. 

    Setup


     

    Once you have completed the preparation steps, it’s time to put everything in place to activate the weld. 

    Step 1: Start by placing both wires parallel in the mold and use the mold handle to clamp it shut. You should feel a click when the clamp is completely closed. 

    Step 2: Next, take some Cadwld Mold Sealer and fill the bottom opening of the mold so the weld material doesn’t escape when the chemical reaction starts. 

    Step 3: It’s important to remember that you want to make sure your mold is level so the welding material flows into the correct channels once it has been ignited. 

    Step 4: Then, place the K cup of welding material in the top of the mold with the ignition tab exposed. 

    Step 5: Attach the electronic igniter to that tab and close the top of the mold.

    Step 6: Step away from the mold and hold the operator button on the ignitor control unit until the ready light turns off. At this point, the reaction will occur.

    Step 7: After the reaction, allow 30 seconds for the mold to cool before removing it from the wires. 

    Now you have a permanent splice between the two copper wires. Below is a demonstration video where we go through these exact steps to create a weld. You can also check out that video by clicking here or going to our YouTube channel.

  6. The Cordage Institute: Fiber Rope Inspection & Retirement Criteria

     

    The Cordage Institute

    When it comes to working at-height, inspecting your equipment can make all the difference in job site safety. We’ve covered rope inspection in a previous blog post. You can find that post by clicking here. This week our Gear Experts® are going to provide a broad overview of the organization that sets standards for inspection.

    The Cordage Institute


     

    Fiber rope standards are established by an organization called the Cordage Institute. The Cordage Institute was founded in 1920 and is comprised of a group of fiber rope manufacturers, their suppliers, and affiliated end-user organizations. While the cordage institute sets a wide variety of standards for a wide variety of uses, the standard that is of interest to our industry is the International Guideline for Fiber Rope Inspection and Retirement Criteria – specifically section 4 (CI 2001-04).

    CI 2001-04


     

    As we mentioned above, section four covers fiber rope inspection and retirement criteria. This section is further broken down into sub-sections that outline the different requirements for an effective inspection and retirement program.

    4.1.1

    Section 4.1.1 states that the user is responsible for establishing a program for inspection and retirement that considers conditions of use and degree of risk for the application. It outlines that a program should include:

    • Assignment of supervisory responsibility. Meaning that an individual should be made responsible for establishing the program, training and qualifying inspectors, and preserving records;
    • Written procedures;
    • Training;
    • Record keeping;
    • Establishment of retirement criteria for each application; and
    • Inspection schedules

    4.1.2

    Section 4.1.2 states that ropes that secure or control valuable assets or whose failure would cause serious damage, pollution, or threat to life warrant more scrutiny than ropes in non-critical use. It goes on to state that if a fiber rope is used in a highly demanding application, with potentially critical risks, the advice of a qualified person should be obtained when developing the specific inspection and retirement program.

    4.1.3

    Section 4.1.3 states that the user should continue to revise and refine the program based on experience.

    CI 2001-4.3


     

    Section 4.3 covers rope inspections logs. We have talked about the importance of a rope inspection log in this previous blog post. This section states “An important tool for rope evaluation is a log. This will include data on the type of rope, time in service and description of intended use. The details of every inspection should be entered in the log as to date, location and conclusions. The log should include a regular inspection schedule”.

    Most rope manufacturers include a rope log with their rope. However, if you don’t think it did, or you have lost it, we provide a free downloadable rope log in our Knowledge Base.

    CI 2001-5.1.1


     

    Section 5.1.1 covers rope tags. This is a tag that is attached to the rope that outlines the rope, model number, manufacturing date, MBS, and manufacturer. If this tag is illegible the rope should be retired immediately. If the rope does not come with a tag you can make your own. Also, using shrink tube is an inexpensive solution to attach your tag to a rope and keep it protected.

    Rope Inspection


     

    Section 6 outlines rope inspection. We took a deep dive into rope inspection in this previous blog post. It also talks about rope care & maintenance – like rope wash which we talked about in this blog post. Last, but not least, it covers proper rope storage. We covered rope storage in this blog post.

    Rope Retirement


     

    If a rope’s tag is illegible or if it no longer passes inspection, it is time to retire the rope and purchase a new one. Rope retirement doesn’t mean just throw the rope back in your truck or trailer, it means cutting the rope into pieces so small that it would no longer be useful for a crew to try and use.

  7. Anti-Vibration 101

    When it comes to working in at-height, industry, and construction there is no shortage of dangers. From the risk of falling, heat stress, and cold stress, to dropped tools and deadly gasses, the job site is a minefield of potential hazards. One lesser-known (or at least less frequently talked about) are the dangers of vibrations. This week our Gear Experts® are going to discuss the dangers of vibrations and how the use of Anti-Vibration Gloves can help protect you.

    Bad Vibrations


     

    When the Beach Boys wrote Good Vibrations, they definitely weren’t talking about the kind created by power tools. Using power tools is common on the job site and hard to avoid. Power tools are great – they make extremely difficult tasks easier and save valuable time by making quick work of tasks that would take a lot longer by hand. But, the battery or plug powered devices are pumping out a lot of power and in turn, create a lot of vibrations when in use. Overexposure to those bad vibrations can lead to Hand-Arm Vibration Syndrome (HAVS).

    Hand-Arm Vibration Syndrome (HAVS)


     

    HAVS is diagnosed in three main components.

    Peripheral Neuropathy of the Hands

    This component can cause a loss of dexterity, tingling, and numbness.

    Secondary Raynaud’s

    This component is sometimes referred to as vibration white finger (VWF) and has been described the BC Medical Journal as the most dramatic manifestation of HAVS. Secondary Raynaud’s produces intermittent whitening of the fingers. It typically starts at the tips of the fingers and will travel up your fingers as the disease progresses. You may also experience tingling, pricking, chilling, burning, or a numbing sensation.

    Musculoskeletal Issues

    This is the broadest and least defined of the three HAVS components. Symptoms of musculoskeletal issues include weakness, pain of the hands, wrists, forearms, and elbows, and discomfort.

    Preventing HAVS


     

    HAVS is a serious condition and has been around for decades, but preventative measures can be taken to reduce the effects of vibrations on your hands and arms. Anti-Vibration Gloves have been specifically designed to help prevent the vibrations made from power tools and heavy machinery from making it to your body. But, as with all equipment, knowing the right ones to use is important.

    ANSI S2.73 // ISO 10819


     

    The ANSI S2.73 standard for anti-vibration gloves outlines testing requirements and certifies that the gloves meet or exceed the requirements.

    This standard requires that the gloves meet the following specifications:

    • Must have a full finger design;
    • Must reduce “medium range frequencies” (also referred to as TM) by at least 10% compared to a bare hand;

  8. 3Z RF Vision Antenna Aligner: Small Cell Mounting

    3Z Small Cell Mounting

    With the 5G rollout in full swing accurate antenna alignment is going to be more important than ever. This week, our Gear Experts® are going to cover the importance of accurately aligning 5G small cell antennas to maximize high-band mmW frequencies and Massive MIMO beamforming antenna performance.

    5G Challenges


     

    5G is a massive leap in cellular technology that will bring near gigabit mobile speeds. It will open up new opportunities for a range of industries from consumer to public health and beyond. But, as with any leap in technology, there are roadblocks that have to be overcome. 5G brings some new challenges that aren’t as prevalent with typical LTE antennas on a tower or monopole.

    Coverage vs Speed


     

    In dense city landscapes, the deployment of 5G will be carried on the backs of small cell antennas that are mounted on buildings, light posts, or any structure that can be used to support an antenna and position it in the direction it needs to be. The reason for this is because of coverage distance.

    Small cell antennas have an extremely powerful signal strength – and they need to in order to transmit 5G. But, as a trade-off for power, the distance they can cover is severely diminished. That means these antennas will need to be positioned closer to the ground.

    Line of Sight


     

    Carriers are using 5G New Radio modeling software to develop their network and rollout plans. But, this software isn’t perfect when it comes to identifying nearfield RF obstacles that could render the antenna useless. That’s where the RF Vision Antenna Aligner from 3Z comes into play. It features a line-of-sight target camera that can help installers both identify and record potential antenna obstructions when performing on-site surveys. Once you’ve achieved a comprehensive antenna alignment with a line-of-sight survey a report is automatically generated of the site for sharing with the carrier.

    Small Cell


     

    The RF Vision is a versatile aligner and fits most antenna types. It features GNSS dual frequency technology to deliver accurate alignment readings – even in high-density urban areas. But, with that being said, aligning small cell antennas still isn’t a walk in the park. Small cell antennas are typically housed in a cylindrical canister which conceals up to 3 directional antennas.

    Alignment can be easier with the use of the small cell reference plate for the strap clamp that comes with the RF Vision. In fact, the small cell reference plate is so simple to use that you simply attach it and line up the tool with the correct antenna. Let’s go ahead and break that down, too.

    Small Cell Reference Installation and Use


     

    The first step when using the small cell reference plate is to install the rubber bumpers to protect the small cell housing. Next, you want to mount the reference plate on the bottom of the strap clamp pointing in the same direction as the rubber bumpers. Please note that you will need to flip the mounting plate for the alignment tool so that it is pointing in the opposite direction of the bumpers and reference plate.

    Once the tool, mounting clamp, and reference plate are securely attached, locate the reference arrow on the bottom of the small cell antenna. That arrow tells you which direction each antenna is facing within the canister. Line the reference plate up with the desired antenna and strap the mounting bracket down tightly so it can’t be moved. Now, you're properly lined up with the antenna and you can proceed with aligning the antenna.

  9. Product Spotlight: 3M SecureFit Safety Helmet

    Protecting your skull is an important part of job site safety. After all, without your head – it’s kind of hard to do anything. This week our Gear Experts® are going to break down the all-new 3M SecureFit X5000 Series ANSI Safety Helmet.

    The Features


     

    Let’s start with the basics of this helmet. Like most standard helmets it features suspension and adjustment options. But 3M has taken these basic features a step further to create a quality helmet that breaks the status quo.

    Suspension

    This helmet features 3M Pressure Diffusion technology in the suspension to increase both comfort and security. In fact, the Pressure Diffusion reduces the force on your forehead by up to 20% when compared to older styles of 3M helmet suspension. The suspension also has been designed to sit lower on the head to further reduce the pressure and increase both comfort and security.

    Adjustments

    What good is a helmet that has comfortable suspension if the helmet doesn’t fit on your head you ask? Well, with 15 different adjustment settings that allow for a range of different height and front-to-back settings, you won’t have to worry about that anymore. Plus, the smooth, turning ratchet suspension system makes the headband adjustments quick and easy.

    Additional Features

    This helmet doesn’t just stop at basic features like suspension and adjustment options. It also includes accessory slots and clips integrated into the helmet that are compatible with a wide variety of 3M accessories. And, it includes a UVicator sensor that is installed on the helmet. The UVicator sensor changes color from red to white over time as it is exposed to UV (ultraviolet) light. Once the color has changed to white it indicates that that the helmet should be retired due to UV exposure.

    Design


     

    You’ll notice as soon as you look at the helmet that it doesn’t look like a traditional safety helmet. That’s because the design is inspired by modern climbing helmets. Who said you can’t be safe while looking cool? And, the brimless design ensures that you have a better awareness of hazards.

    Standards


     

    Now we get to the most important part – standards. After all, you need to know if this helmet is something that you can use on a specific job site. All 3M SecureFit X5000 Series helmets meet ANSI Z89.1-2014 and are Type 1 helmets. We covered helmet standards in more detail in our Safety Helmets 101 blog post. We also have a free Safety Helmets 101 poster that you can download from our Knowledge Base.

    Options


     

    This helmet comes in a wide variety of options. First, you can choose if you want standard or reflective. Then you can choose whether you want a vented or non-vented helmet. The last thing you can choose is color. This helmet is available in a total of 8 colors.

    For more information about the 3M SecureFit X5000 Series ANSI Safety Helmet you can view the product here or click here to contact one of our Gear Experts®.

  10. Product Spotlight: PPG Keeler & Long Anodic Self-Priming Cold Galv

    PPG is a household name. Primarily known for their paint and coatings, PPG isn’t a name that comes to mind for most people when they are thinking about cold galv. But, through their Keeler and Long brand, PPG offers a full line of Self-Priming Cold Galvanizing Compound. This week, our Gear Experts® are going to break down Keeler & Long Anodic Self-Priming Cold Galvanizing Compound.

    Cold Galv 101


     

    Cold galvanizing compound (cold galv for short) is a single component zinc coating that is used to protect bare steel from rust and corrosion. It is applied like paint, but it’s not paint. It actually gives the same protection as hot dipped galvanizing and it also makes painting a tower easier. Cold galvanizing compound acts as an active coupling to the bare steel parent metal to form an electrolytic bond. In the presence of an electrolyte (aka moisture) the zinc dust in the cold galv will sacrifice itself to protect the steel.

    For a more complete breakdown on cold galv, surface prep, application methods, and more click here to check out our full Cold Galv 101 blog post.

    Keeler & Long Anodic Self-Priming Cold Galvanizing Compound


     

    The Keeler & Long Anodic Self-Priming Cold Galvanizing Compound is a rust inhibitive coating designed for corrosion protection in a single coat. Keeler & Long Cold Galv is self-priming in many applications and will dry when applied in temperatures down to 35 degrees Fahrenheit as long as the temperatures are expected to rise over the following months. The Keeler & Long Cold Galv Compound is usable for coating weathered galvanized or previously painted surfaces of transmission or communication towers, poles, substation structures, chain link fencing, buildings, and bridges.
